Personality
By his classmates, Sakuya is known as the class clown, as he is always making jokes and telling rumors of nearby vampires in an effort to scare his friends. The only friend who knows his true identity, however, is Mahiru.

History
In his past, Sakuya's older sister was driven to suicide by their parents, who said it was an accident in order to receive money from life insurance. Sakuya knew the truth but was forced to lie about the situation, which was also his first of many lies. Before her death, Sakuya's sister made their parents promise not to hurt Sakuya.
